The BC 547 Transistor is a bipolar junction transistor (BJT) NPN-Type and is often used to drive relays or LED drivers when used as a switch but is also widely used to amplify signals.
NPN
Gain value of BJT BC547 is between 110 to 800.The maximum current able to flow through the Collector pin is 100 mA, We can not therefore connect loads which consume more than 100 mA using this transistor.To bias a transistor we must supply a base pin with current, The current (IB) is limited to 5 mA.Conclusion with statement 2 and 3 is, 0.5 mA base current IB drive 10 mA Collector current IC and 5 mA IB can drive 100 mA IC.If this transistor is fully biased then a maximum of 100 mA can flow through the collector and emitter. This stage is named Region of Saturation.When the base current is removed the transistor will turn off completely, This stage is known as the Cut off Region.
